Application filed July 3, 1916. Serial No. 107,220. e

To all whom it may concern:

Be it known that I, ISAAC Snow, a citizen 1 of the United States, and resident of Lawtransfer operation.

rence, in the county of Essex and State of Massachusetts, have invented an Improvement in Transferrers for Automatic Filling Replenishing Looms, of which the following description, in connection 'with'the'accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to the transferrer of looms provided with automatic filling replenishing mechanism. In such looms the supply of fresh filling carriers is maintained in a feeder or hopper and when the call comes for replenishment, a pivoted transferrer is moved downwardly and acts to transfer a fresh filling carrier from, the hopper into the shuttle which is then beneath the hopper on the lay. The transferrer usually contacts with the butt of the filling carrier and also with a point at or adjacent the tip but the main force applied by the transferrer is to the butt. As a result and as the filling carrier is not positively held by the transferrer, the filling carriers are sometimes improperly placed in the shuttle by the transferrer and sometimes the filling carrier is not properly seized or acted upon by the transferrer during the In either case breakage occurs. p

- It is the object of the present inventionto provide a form of transferrer which upon transfer movement will come into contact with the freshfilling carrier both at the butt 'and at or adj acentthetip and which will be provided with a means for positively locking the tip of the filling carrier to the transferrer so that the filling carrier will be transferred accurately and surely into the shuttle.

The drawings illustrate so much of the mechanism of an automatic filling replenishing loom and the preferred formvof the invention embodied therein as is necessary to a disclosure of the said invention.

, Fig. 2.

Since this invention relates solely to the transferrer, it is unnecessary to illustrate or todescribe. in detail the automatic filling replenishing loom of which it forms a part and of which the construction and operation is familiar to those skilled in the weaving art.

For convenience of illustration, there is herein shown the hopperstand 1 from which rises the hopper 2 and upon which are ro .tarily mounted the disks, one of which 3 is shown. The disk 3 is provided with peripheral seats 4: in which are mounted the butts of the supply of fresh filling carriers 5 while the tips are mounted or supported i the opposite disk not illustrated.

The filling carrier to be transferred is brought by the rotation of the hopper into contact with the abutment 6 and in this p0- sition is held in the hopper by the yielding bobbin support 7.. When the running filling breaks or becomes entirely or partially exhausted and filling replenishment is called for, mechanisms are-set into operation which cause the transfer of this filling carrier rest ing against the abutment 6 from the hopper downwardly into the shuttle which is then .on the lay and beneath the hopper, the spent filling carrier being simultaneously ejected.

The immediate instrumentality concerned in-the transfer is the so-called transferrer which is herein shown as pivotally mounted at 8 on the hopper stand, and of the shape of a bell crank lever. The transferrer projects between the disks of the hopper and In its normal inactive position the head 9' of the transferrer extends directly above the butt of the filling carrier in position for transfer.

In the construction illustrated as embodying the present invention, the head 9 of the transferrer has extending laterally therefrom in the direction of the tip of the filling carrier, an arm bent downwardly at its free end and recessed at 11. The proportions are such that when the transferrer comes into contact with the filling carrier and the head 9 contacts with the butt, the recess 11 will engage the fillingcarrier at the tip. A rock shaft 12 is journaled in the head 9 and extends in general parallelism with said arm and is preferably journaled in the depending end of the arm 10. This rock shaft 12 is provided adjacent the end of the arm 10 and adjacent the recess 11 with a finger 13 curved at its lower end to conform in general with the curvature of the recess and the curvature of the tip of the filling carrier.

' A tail piece 14 projects from. the shaft 12 adjacent the head, extends beneath the head, and fits Within a recess 15 in the bottom of the head. As illustrated, this tail piece 14 projects downwardly from the shaft 12, then rearwardly and then laterally beneath the head. A helical spring 16 is mounted on the shaft 12 and secured at one end to a collar 17, adjustable by a set screw 18 on the rock-shaft and is secured at its opposite end 19 t0 the transferrer arm. This spring acts normally to maintain the rock-shaft in the position shown in Figs. 1 and 2 with the tail piece 14 below the plane of the bottom of the head 9 and withthe finger 13 forward of the recess 11.

The operation of the parts will now be apparent. Upon the call for filling replenishment, the. transferrer is thrown downwardly. As it moves downward the tail piece 14 comes into contact with the butt of the filling carrier and the recess 11 passes over the tip. As the movement continues, the tail piece 14 passes into the recess 15. in the head of the transferrer-and the finger 13 closes against the tip now in the recess 11 looking it within said recess. As themovement continues, the transferrerfhead actingv against the-butt and the recessed endofthe farm lOacting against the tip, forces the filling, carrier out from the hopper and the transfer movement is completed with the fillingcarrier locked to the transferrer by the finger 13. Thus the filling carrier is transferred accurately and surely into its proper position in the shuttle and all danger of breakage from improper positioning of the filling carrier during transfer is eliminated. Upon initiation of reverse movement of the transfer, the spring 16 rocks the rock shaft 12 causing the finger 13 to swing away from the recess and the filling carrier is thus automatically released.

Having fully described my invention, what I claim as new and Patent is:

1. In a loom provided with automatic fill ing replenishing mechanism, a hopper contaming a supply of fresh filling carriers, a transferrer movable on the call for filling replenishment to transfer a filling carrier from desire to secure by Letters the hopper into the shuttle, the said transferrer comprising a head operating at the gagement with the head and the finger-away from the recess, whereby as the transfer movement takes place the said shaft is rocked by the buttof the filling carrier engaging the tail piece to cause the finger to engage the tip and lock it within said recess, and whereby upon initiation of the reverse movement of the transferrer the filling carrier is automatically released.

2. In a loom provided with automatic filling replenishing mechanism, a hopper containing a supply of fresh filling carriers, a transferrer movable on the call for filling re plenishment to transfer a filling carrier from the hopper into the shuttle,'the said transferrer. comprising ahead operating at :the butt of the filling carrier, an armextending laterally from said head andrecessed at its end to engage the tip of the filling :carrier,

a rock shaft journaled in said v headjandextending in general parallelism with saidarm, a finger projecting from said shaft' r-adja'cent theend of the arm,'a tailpiece {projecting fromsaid shaft and extending beneathv the head, and a helical spring on said shaftconnected at one end thereto and at the other end to said head and acting normally torock the shaft and maintain the tail piece out of engagement with the head and the finger away from the recess, whereby as the trans fer movement takes place the said "shaft is rocked by the butt of the filling carrier engaging the tail piece to cause the finger to engage the tip and lock it within said recess, and whereby upon initiation of the reverse movement of the transferrer the filling carrier is automaticallyvreleased.

In testimony whereof, I have signed my name to this specification.

ISAAC SNOW.
